Ectopic renal ectopic

Renal ectopic means that a well-developed kidney cannot reach the normal position in the retroperitoneal renal fossa. Ectopic ureteral opening refers to the opening of the ureter outside the normal position. Renal ectopic should be distinguished from renal sagging, which means that the kidney is initially in a normal position and has a normal blood supply, but for some reason the downward movement occurs, and the ectopic kidney is not in the normal position from the beginning. Ectopic kidneys are commonly found in the pelvis, popliteal fossa, abdomen, chest, or cross-ectopic kidneys. Ectopic opening of the ureter is mainly manifested by normal intermittent urination with continuous leakage and repeated urinary tract infections. Men usually open the posterior urethra, ejaculation duct, seminal vesicle, etc. Women can open the urethra, vagina, vestibule and cervix. About 80% of the ureteric ectopic is found in the upper ureter in a double ureter. More than 80% of double kidney and double ureter with ureteral ectopic is seen in women, while single ureteral ectopic is more common in men. About 10% of ureteric ectopic is bilateral.
